I am using the VOF model.<\/p>\n<p>I was wondering what is the correct way to model a far-field boundary condition for the walls of my computational domain. I have a pressure inlet that defines the free surface level, a pressure outlet with the same water surface level and the symmetry wall, but the other three walls should be &quot;far-field&quot;. Is the right way to do it a pressure outlet? I am getting reversed flow even though changed the definition of reversed flow to flow in the negative x direction (opposite to the freestream velocity).<\/p>\n<p>Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-160911","topic","type-topic","status-closed","hentry","topic-tag-boundary-conditions","topic-tag-fluent","topic-tag-marine-1","topic-tag-vof-model"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_view_count":["236"],"_bbp_likes_count":["0","0"],"_bbp_forum_subforum_count":["0"],"_btv_view_count":["562"],"_bbp_subscription":["241413"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160911"],"_bbp_forum_id":["27792"],"_bbp_engagement":["118","199","201982"],"_bbp_voice_count":["3"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["187383"],"_bbp_last_active_id":["187383"],"_bbp_last_active_time":["2021-08-02 14:58:25"]},"test":"pol-martorell-gilcranfield-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160911","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160911\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160911"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
